solid, weather resistant casing ; very good image quality in the frame centre ; sensible image quality on the edge of the frame ; imperceptible longitudinal chromatic aberration ; low lateral chromatic aberration ; lack of problems with spherical...

fickle autofocus performance in more difficult conditions ; a tad too high astigmatism ; too distinct vignetting

Excellent sharpness ; Fast and silent AF ; Highly effective OIS ; Very well controlled CA ; Close focusing ; Great handling ; Compact design ; Weather Resistance

Edge performance dips at longer focal lengths

This is a very well made lens with lovely bokeh and a high level of sharpness. Flare, CA and distortion are all but abolished. Images look clean and crisp and sharpen well in Photoshop. The lens is easy to use, the OIS system enables hand held shooting...

Superb optics. Long telephoto reach. Weather-resistant design. Teleconverter compatibility. Includes removable tripod foot and hood.

Rapid autofocus system ; 5-stop optical stabilization ; Extensive weather-seals

No AF-on/hold buttons ; Fairly weighty at 1.4kg

Thanks to the crop factor of Fujifilm’s X-mount mirrorless cameras, this lens delivers radical reach of up to 609mm in full-frame terms. It really covers the distance in action, sports and wildlife photography, for which the super-fast autofocus system...

Brilliant lense. Wonderful quality photos are the result . Tate this a worthwhile buy even at its price

Not The lightest

Image quality is very good for the price, even with the 1.4 teleconverter. A bit of a lump compared with Micro 4/3rds super telephotos but the image quality of the lens and XT2 sensor more than justifies this.

AF slows noticeably when using 1.4 TC

Typical high quality Fuji build. Everything works smoothly. Auto focus is fast and accurate ( used on an XT2). Image quality compares with the best high quality telephoto zooms.

Though not a cheap plastic build it is indeed mainly plastic. Unique for Fuji high end lenses. I guess that does give a weight advantage though and it can be argued that modern advanced plastics are at least as good as metal alloys. I'm just a bit old...

Its Plastic instead of the usual Fuji metal.
